The fastest speed ever measured for a tennis ball served by a player was 263 km/h. The distance of the tennis court from one end

Paha777 [63]

Answer:

0.3257 seconds

39.67 m/s

Explanation:

Speed = 263 km/h

Converting to m/s

$1\ km/h=\frac{1}{3.6}\ m/s$

$263\ km/h=263\times \frac{1}{3.6}\ m/s=\frac{1315}{18}\ m/s$

Distance to travel = 23.8 m

Time = Distance / Speed

$Time=\frac{23.8}{\frac{1315}{18}}=0.3257\ s$

The time taken to go from one end of the court to the other is 0.3257 seconds

Time = 0.6 s

Speed = Distance / Time

$Speed=\frac{23.8}{0.6}=39.67\ m/s$

The speed of the tennis ball is 39.67 m/s

hoa [83]

Here are the observations

Sugar:-

Sugar is soluble in water
so It will dissolve in water .

Corn syrup:-

Corn syrup is also basically a sugar.
It will dissolve in water too .
If we shake the mixture in glass then corn syrup will be dissolved.

Oil:-

Oil is not soluble in water
Hence it won't dissolve in water.
It will float over water and make two layers
